Structural assembly for vehicles
A structural assembly for a vehicle includes a structural member extending longitudinally. The structural assembly also includes an insert disposed within and extending longitudinally along at least a portion of the structural member and having at least one corrugation to act as a crush initiator during an axial impact on the structural assembly.
1. A structural assembly for a vehicle comprising:
a structural member extending longitudinally; and
an insert disposed within and extending longitudinally along at least a portion of said structural member, said insert having a pair of side walls extending longitudinally and a web extending between said side walls, each of said side walls and said web having a plurality of corrugations spaced longitudinally, said corrugations in said web being non-aligned with said corrugations in said side walls, said corrugations act as a crush initiator during an axial impact on the structural assembly.
2. A structural assembly as set forth in claim 1 wherein said insert has a cross-section complementary to a cross-section of said structural member.
3. A structural assembly as set forth in claim 1 wherein each of said corrugations has a projection portion extending inwardly.
4. A structural assembly as set forth in claim 1 wherein said structural member has marginal flanges extending from said side walls.
5. A structural assembly as set forth in claim 1 wherein said structural member is a rail extending longitudinally.
6. A frame for a vehicle comprising:
a pair of rails extending longitudinally and having a forward portion and a rearward portion; and
at least one of said forward portion and said rearward portion having a structural assembly;
wherein said structural assembly comprises a structural member and an insert disposed within said structural member, said insert having a pair of side walls extending longitudinally and a web extending between said side walls, each of said side walls and said web having a plurality of corrugations spaced longitudinally, said corrugations in said web being non-aligned with said corrugations in said side walls, said corrugations act as a crush initiator during an axial impact on said structural assembly.
7. A frame as set forth in claim 6 wherein each of said corrugations has a projection portion extending inwardly.
8. A frame for a vehicle comprising:
a pair of rails extending longitudinally and having a forward portion and a rearward portion; and
at least one of said forward portion and said rearward portion having a structural assembly;
wherein said structural member has a pair of side walls extending longitudinally, a web extending between said side walls, and marginal flanges extending from said side walls, each of said side walls and said web having a plurality of corrugations spaced longitudinally, said corrugations in said web being non-aligned with said corrugations in said side walls, said corrugations act as a crush initiator during an axial impact on said structural assembly.
